Distribution
Found mainly in Spain and Portugal. A small population in adjacent south-western France.
A small population occurs in the north of Morocco especially in the eastern Rif montains areas. Unfortunatly no scientific studies have been carried out to evaluate the status of the Moroccan population.
Taxonomy
Subspecies
Two subspecies recognized[1]:
- P. i. biscayensis in northern Portugal, northern Spain and France
- P. i. ibericus in central and southern Portugal and south-western Spain
Has been considered conspecific with Common Chiffchaff in the past.
Habitat
Behaviour
Diet
Breeding
Vocalisation
Contact call a whistled “piu” or “pew” with downward inflection, similar in tone to contact call of Eurasian Bullfinch, in autumn has short, shrill “peep”, “seep” or “weep”, like that of subspecies abietinus and tristis of Common Chiffchaff. Song a hesitant repetition of rising and falling notes, slower than that of similar species Common Chiffchaff, “chi chi chi tchui tchui tchui tchu tchu tchu”, with descending tones of triplets and usually given at an inreasingly faster pace. Breeding birds may give an additional dry “chep” or “jep” at the start. Some in the north of it's range (Pyrenees) give “mixed” songs incorporating segments of Common Chiffchaff song, but usually still closer to normal song for the species. High percentage of males react to songs of Common Chiffchaff (but not reciprocated) and Canary Islands Chiffchaff. Females largely ignore the song of the Common Chiffchaff, whereas females of latter species react strongly to songs of males of their Iberian cousins.
